Diabetes Mellitus, Type 1
Conditions
Brief summary
The investigators conducted this randomized-controlled trial to assess the effect of oral omega-3 supplementation on glycemic control, lipid profile, albuminuria level, kidney injury molecule-1 (KIM-1) and carotid intima media thickness (CIMT) to participants who were pediatric patients with T1DM and diabetic nephropathy.
Detailed description
Management of diabetic kidney disease (DKD) mainly consists of correction of hyperglycemia, hypertension and dyslipidemia as well as modification of lifestyle. Primary prevention represents prevention from normoalbuminuria to microalbuminuria, while secondary prevention represents prevention from microalbuminuria to macroalbuminuria. Multiple interventional managements with control of blood glucose, blood pressure and lipid, and smoking cessation can significantly improve the prognosis of cardiovascular events and slow down the progression of renal disease. Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) derived from fish oil. Numerous studies have evaluated the potential beneficial effects of omega-3 fatty acids on inflammatory, autoimmune, and renal diseases. Due to their anti-inflammatory effects, omega-3 fatty acids have been suggested to protect against kidney damage. Omega-3 fatty acids can reduce proteinuria in patients with chronic glomerular disease and slow immunoglobulin A (IgA) nephropathy. However, the information about the effects of omega-3 fatty acids on kidney function, particularly in diabetic kidney disease still lacks consensus . No previous study assessed the role of omega-3 fatty acids in diabetes associated complications in particular diabetic nephropathy and subclinical atherosclerosis among pediatric patients with T1DM and there is insufficient evidence to recommend its supplementation for those patients. Therefore, the investigators conducted this study to investigate the role of omega-3 fatty acids as an adjuvant therapy for participants who had diabetic nephropathy in children and adolescents with T1DM and assess its relation glycemic control, microalbuminuria, kidney injury molecule-1, lipid levels and carotid intima media thickness as an index for subclinical atherosclerosis.
